ANTISKID ATTACHMENT.

Application filed March 10, 1920. Serial No. 364,807.

To all whom it may concern Be it known that I, SoL C. SHERRY, a citizen of the United States, and a resident of IVest Englewood, in the county of Bergen and State of New Jersey, have invented a new and Improved Antiskid Attachment, of which the following is a full, clear, and exact description.

This invention relates to improvements in antiskid attachments, an object of the invention being to provide an attachment manufactured and sold at a reasonably low price and which will be strong and durable 1n use. 7

With these and other objects in view the invention consists in certain novel features of construction, and combinations and arrangements of parts, as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings Figure 1 is a view in side elevation illustrating three of my improved attachments in position on a wheel of the ordinary Ford yp Fig. 2 is an enlarged view in section on the line 2-2 of Fig. 1; 1

Fig. 3 is a View in section on the line 3-3 of Fig. 2.; and

Fig. 4: is an end view of the attachment showing it in position on the tire.

The wheel A illustrated is of the ordinary Ford type having a hub 1 connected by spokes 2 with the felly 8. The rim is secured around the felly and the tire 5 1s supported in the rim.

While I preferably employ three attachments on each wheel, it is obvious that I do not limit myself to any particular num ber and as all of the attachments are preoisely alike, the description hereinafter of one will apply alike to all.

In forming my improved attachment I employ two metal plates 6 and 7 whlch are precisely alike, but reversely positioned so that they can be formed alike and do not require the provision of rights and lefts,

hence cheapening the cost of manufacture. The plates 6 and 7 are of relatively heavy sheet metal and are of somewhat triangular shape. In other words, they are narrowest at their inner ends and increase in width to their outer ends and are made with central, longitudinal, semi-cylindrical bearings 8 which are located at opposite sides of the spokes 2 and at their inner ends are flared outwardly, as shown at 9, to conform to the outward flare or enlarged inner ends 10 of the spokes 2.

These plates 6 and 7 are made with outwardly projecting lips 11 projecting at right angles to the plates and bearing against the felly 3 of the wheel, it being understood that the semi-cylindrical bearing portions 8 at their outer ends extend across the inner face of the felly, and hence, the attachment is held against longitudinal movement on the spoke because of its engagement with the enlarged inner end 10 of the spoke and its engagement with the folly.

A casting 12 is provided against the outer and lower portion of one of the plates 6 or I 7 and is made with a laterally offset portion 13 to fit around the semi-cylindrical bearing 8 and with laterally projecting tongues 14 located against the tongues 11 to strengthen the latter. This casting 12 1s secured by rivets or other sultable securing devices 15 to the outer face of one of the plates, and bolts 16 are projected through the plates and secured by nuts 17 to securely clamp the plates together 1n pos1- tion on the spoke. a,

. The plates 6 and 7 are further strengthened by longitudinal corrugations 18 1n any desired number, and as above stated, these plates may be made of metal of sufliclent thickness to withstand the strains to which they are necessarily subjected. The outer ends of the plates 6 and 7 and the cast ng 12 are recessed, as shown at 19, to receive the rim 4 and a portion of the tire 5 and provide at opposite sides of the t1re radially projecting webs or blades 20 which are adapted to dig in the snow or mud and give the wheel a gri on the surface so as to 1mprove the traction of the wheel and permlt a driving of the car even in the worst of weather. A chain or other flexible device 21 is located around the tire and is secured at its ends by bolts 22 or other securing devices to the webs 20. This chain 21 prevents 5 slipping on smooth surfaces and hence facilitates the traction of the wheel.

The attachments can be conveniently carried in the car and when desired for use, can be quickly attached to the spokes of the wheel by the employment of an ordinary wrench and will provide blades or webs projecting laterally from opposite sides of the wheel to afford a grip on the snow or mud to facilitate the driving operation of the car.

Various slight changes might .be made in the general form and arrangement of parts described without departing from the invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

I claim: a

1. An attachment of the character described, comprising a pair of transversely positioned plates, each plate having a narrow concave longitudinal surface adapted to engage the spoke of a wheel, said plates adapted to be positioned on opposite sides of the spoke, means for securing the plates together, and said plates having outwardly -projecting webs adapted to be positioned against the wheel felly and adapted to span the wheel tire.

2. The combination with a wheel and tire, of an attachment comprising a pair of transversely positioned plates, each plate having a narrow concave longitudinal surface adapted to engage the spoke of a wheel, means for securing the plates together, said plates recessed at their outer portions to receive the wheel tire and provided with laterally projecting webs at opposite sides thereof, tongues on said plates projecting at right angles thereto and located beside the wheel felly, an anti-skid chain connecting the webs and means for securing the chain.

3. The combination with a wheel and tire of an attachment .comprising a pair of plates transversely positioned with respect to the tire, each plate having a narrow concave longitudinal surface adapted to engage the spoke of a wheel, means for securing the plates together, said plates recessed at their outer portions to receive the wheel felly and provided with laterally projecting webs at opposite sides thereof, a reinforcing casting superimposed upon one of the plates and secured thereto, the casting and the plate having tongues projecting at right angles thereto and located beside the wheel felly.
